The human skin mask, stained with lividity, had a half-smile on it as the man walked forward with his hands and feet moving in unison.

Xia Chuhe carried the corpse and followed him to the door.

Outside the door is a corridor with other rooms on both sides, somewhat similar to the layout of a factory workshop.

The man pointed to the door at the end of the corridor: "Go out from there, and you'll reach the residential area."

Thank you.

The man clenched his fists, deciding that once Xia Chuhe walked out of the door, he would press the alarm button and have the guards arrest this arrogant evolved human!

Xia Chuhe moved closer to the man, who was so startled that he took two steps back.

Xia Chuhe chuckled: "As a thank you, let me tell you a little secret: the raw material for black clay is the corpse of a non-evolved being."

"A corpse?" The man subconsciously raised his hands, glanced at them, and looked on in surprise and uncertainty.

"Aren't you curious why the base controls the entire lives of non-evolved individuals, even their corpses after death? The answer lies in the place where you work every day, right above your head."

Xia Chuhe stepped forward: "After you die, the upper class will throw your corpse into the corpse-evolution pool, extract the trace elements from your body, and add them to the nutrients you consume every day. Your flesh will be corroded into a pulp, mixed with black soil, and flow out to become black clay, which will then be used as fertilizer by your companions."

"No, impossible..." the man muttered to himself, his face pale.

"Haven't you ever picked up bone fragments from the fertilizer? Haven't you ever suspected the origin of the black clay?" Since the life support filter is damaged from time to time, there must be some undissolved bone and flesh mixed in with the black clay.

The man had seen white bone fragments in the fertilizer more than once, and he had thought about it a lot. But after working for a long time, people become numb, and what seemed strange and intriguing at first becomes commonplace day after day.

With Xia Chuhe's reminder, the white bone fragments, strange joints, and fine hairs that had appeared in the past suddenly had a reasonable explanation.

"No, no, it's not like that, it's not..." The man looked at the black clay's outlet in horror, "A dead person, a corpse..."

Xia Chuhe, her face covered in lividity and her body stained with blood, looked like a demon crawling out of hell. Her voice carried a hint of playfulness and pleasure: "Tell me, did you mix any of your neighbors in the fertilizer you made today?"

The man was even more terrified, almost curling up into a ball.

Xia Chuhe raised his hand and knocked him unconscious, then changed into his work clothes and strode away.
